Dolphins also speed most of their life UNDER the watersurface, instead of on the watersurface as sailboats do.

Otherwise surface ships would look like submarines do and they don't.

These animals must have wonderful hydrodynamic shape. I have sailed at ten knotts and had a dolphin pacing me a metre off my bow for several ks and not even look like its tail is moving.


He was riding the pressure zone of your bow wave. In effect, the portion of water directly in front of your boat moves forward with almost the same speed as the hull. The dolphin "feels" like he is just hovering in his particular volume of water while he and the volume of water are pushed along by the boats hull. Dolphin cover many many many nautical miles like in front of oceans freighters, with a minimum in effort..
